The Siemens 3RT2916-1JJ00 is a genuine SIRIUS surge suppressor module featuring a varistor with integrated LED indication, designed to protect contactor coils and control circuits from switching-induced voltage spikes. This front-mounted accessory is specifically engineered for Siemens SIRIUS 3RT2.1 contactors and 3RH2 auxiliary contactors (Size S00), helping improve operational reliability and extending the life of connected control equipment.
Designed for 24–48V AC (50/60 Hz) and 12–24V DC control voltages, the 3RT2916-1JJ00 effectively suppresses transient overvoltages generated when contactor coils are energized or de-energized. By limiting voltage peaks, it helps protect PLC outputs, relays, timers, sensors, and other sensitive automation devices from electrical stress and potential damage.
A key feature of this suppressor is its integrated LED status indicator, which provides immediate visual confirmation of coil energization and control circuit operation. This simplifies commissioning, troubleshooting, and maintenance while improving visibility inside industrial control panels and automation systems.
The module features a compact front-mount clip-on design, allowing fast installation without additional wiring modifications. Suitable for mounting in any position, it is designed specifically for S00-size Siemens SIRIUS contactors, making it ideal for motor control centers (MCCs), OEM machinery, HVAC installations, and industrial automation applications where panel space is limited.
By reducing switching transients and electromagnetic interference (EMI), the 3RT2916-1JJ00 helps prevent nuisance tripping, minimizes contact wear, improves control circuit stability, and enhances overall system performance. Manufactured according to Siemens quality standards, it delivers dependable long-term protection for industrial control systems.
As part of the trusted Siemens SIRIUS 3RT29 accessories range, the 3RT2916-1JJ00 Varistor with LED Surge Suppressor provides reliable coil protection and seamless compatibility with Siemens motor control and automation products.
